The revenue neutrality of it. Yes, I do understand. But the challenge is not only nationally, but our largest competitor is the United States and except for California, there is no carbon pricing across the United States. They may have pollution taxes, but when Canada has a carbon tax and a pollution tax, now you're starting to tilt the playing field against Canadian businesses. That's why I'm a strong proponent of a North American approach to addressing not only greenhouse gas emissions, but addressing the non-greenhouse gas emissions that I think, for the most part, you've been referring to.
